The safety of property and people against risks and electrical faults is essentially ensured by an earthing system. The essential element of the latter is the electrical resistivity of the soil. This is influenced by several factors. In this work, we used the georeference coordinates of the point (A), state of nature the day before the measurement (B), state of nature on the day of the measurement (C), and the ambient temperature at the measurement point (D). 9513 in-situ measurement samples on selected sites in Lomé constitute the database.

Multifunctional excipients are also called all-in-one excipients and are made using co-processing technology. Co-processing is a way to enhance individual excipient physical properties like bulk density, texture, particle size, flowability, and functionality like tablet hardness, weight uniformity, drug uniformity, disintegration, and dissolution profile.

Density and speed of sound were measured earlier by us for binary liquid mixtures formed by Benzonitrile, Chlorobenzene, Benzyl chloride and Benzyl alcohol with Benzene at temperature range 298.15 to 313.15 K and atmospheric pressure over the whole concentration range. Pseudo-Gruneisen parameter and internal pressure were derived from the measured values of density and ultrasonic velocity.

In modern architecture, people want to create impressive and intricate buildings. However, due to limited land and a growing population, especially in countries like India, it has become necessary to build taller structures. As buildings go higher, they face challenges from strong winds. This can be risky, especially if the building's shape is irregular, as it can lead to twisting forces and wind induced vibrations that pose a threat to the structure, human lives, and resources. Therefore, it's crucial to carefully study and understand these forces during the design process.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is an increasingly significant health concern due to its widespread occurrence, heightened risk factors, and significant mortality rates. To address this issue, researchers have focused on utilizing the blood oxygen saturation (SpO2) signal to analyze the occurrences of apnea or hypoventilation episodes during sleep, resulting in the development of the apnea-hypopnea index (AHI). In order to extract relevant information from the SpO2 signals, 35 Time Domain characteristics have been identified and studied.

Renewable energy use is still a viable option for people when it comes to protecting the environment and promoting sustainable development. This is the reason why some people in the commune of N’Zérékoré have opted for the use of solar panels as sources of energy. Although the use of these solar panels is considered an alternative solution to energy problems, it is clear that the performance of these solar panels after installation is negatively influenced by meteorological parameters such as temperature, humidity and precipitation.

Teaching is a noble profession and our country has seen renowned teachers in various fields. Teaching Profession has evolved over the years and the demands of the profession has evolved over the years and the demands of the profession varies at different levels as for schools, colleges, professional colleges etc., Different schools promise global teaching with local knowledge etc., not being able to draw the line in the dynamic education scenario. NEP calls for nationalization of curriculum, while the states call for regionalization.

Entanglement is a key resource in the field of quantum computation and quantum technologies. One has to deal with measurement error-mitigation in the present day Noisy Intermediate-scale Quantum (NISQ) processors so as to witness advantages offered by entanglement. In this paper we implement Bell state measurements in IBM open access 7-qubit quantum processor ibmq_nairobi and mitigate errors incurred. We evaluate fidelities of all four Bell states (theoretical) with the ones retrieved experimentally before and after measurement error-mitigation.

The generalized evolution of the level of road traffic in number and characteristics, associated with overloads, today leads to an underestimate of the loads due to traffic when designing road structures. Consequently, this under-evaluation of the aggressiveness of traffic is accompanied by early appearances of damage to the roads and at the same time causing enormous budgetary expenditure on maintenance and rehabilitation.

In this work, we are interested in the mathematical analysis of a model of a bioreactor based on the results of a model already implemented ADM1. It is an observability analysis and estimation scheme for specific growth rates for an anaerobic digestion process of cow dung. A 1- stage model of 3 dynamic states is assumed describing all anaerobic digestion with a different population of microorganisms, and the evaluation of biogas production (methane + carbon dioxide).
